Description

Technical Field

[0001] The utility model relates to the technical field of tee pipe fittings, in particular to a groove type equal-diameter tee. Background Art

[0002] Tee, also known as pipe tee or tee pipe fitting, tee joint, etc., is mainly used to change the direction of fluid. It is used at the branch pipe of the main pipeline. It can be divided into equal diameter and different diameter. Same diameter tee: the tee with the same diameter of the main pipe and the branch pipe, different diameter tee: the tee with the branch pipe diameter smaller than the main pipe diameter.

[0003] When the existing equal-diameter tees are in use, the tightness of the butt joints is relatively poor, and they are prone to loosening and leakage after long-term use. In addition, there is no corresponding support between the ends, which makes the overall strength of the tee low and is not conducive to people's use. Therefore, those skilled in the art provide a grooved equal-diameter tee to solve the problems raised in the above background technology. Utility Model Content

[0005] To achieve the above object, the utility model provides the following technical solution: a grooved equal-diameter tee, comprising a first connecting pipe, a second connecting pipe is welded to the side of the first connecting pipe, first support rings are welded to the outer rings of both ends of the first connecting pipe, and a second support ring is welded to the outer ring of the second connecting pipe;

[0006] The two ports of the first connecting pipe and the outer ring of the port of the second connecting pipe are both provided with threaded grooves, and elastic telescopic parts are slidably installed inside the first supporting ring and the second supporting ring, and the elastic telescopic parts are abutted against the end of the pipe fitting of the grooved equal-diameter tee.

[0007] Preferably: the elastic telescopic part includes a sliding rod slidably installed inside the first support ring or the second support ring, the end of the sliding rod close to the grooved equal-diameter three-way port is connected to a sealing gasket, the end of the sliding rod away from the grooved equal-diameter three-way port is connected to a retaining ring, and a spring mounted on the outer ring of the sliding rod is installed between the retaining ring and the first support ring or the second support ring.

[0008] Preferably, four groups of sliding rods and springs are slidably mounted inside the first support ring and the second support ring and are equidistantly arranged in a circle around their respective axes.

[0009] Preferably, a first connecting rod is installed between the first supporting ring and the two groups of second supporting rings, and a second connecting rod is connected between the two groups of the first supporting rings.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the butted pipe fittings can push the sealing gasket, the sliding rod and the retaining ring to move during installation, and the retaining ring drives the spring to expand and contract. The sealing gasket can improve the sealing performance of the connection between the pipe fitting and the grooved equal-diameter tee port, and the spring can provide elastic force for movement of the threaded connection, thereby increasing the friction of the threaded connection and improving the tightness of the connection between the grooved equal-diameter tee and the pipe fitting.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2In an embodiment of the utility model, a grooved equal-diameter tee comprises a first connecting pipe 1, a second connecting pipe 2 is welded to the side of the first connecting pipe 1, first support rings 3 are welded to the outer rings of both ends of the first connecting pipe 1, a second support ring 4 is welded to the outer ring of the second connecting pipe 2, thread grooves 5 are provided on the outer rings of the two ports of the first connecting pipe 1 and the ports of the second connecting pipe 2, elastic telescopic parts are slidably installed inside the first support ring 3 and the second support ring 4, and the elastic telescopic parts are abutted against the ends of the pipe fittings connected to the grooved equal-diameter tee.

[0019] When in use, the inner ring of the pipe fitting that is docked with the grooved equal-diameter tee is threadedly connected to the outer ring of the grooved equal-diameter tee port through the threaded groove 5. The end of the butt-jointed pipe fitting pushes the elastic telescopic part to move during installation. When the butt-jointed pipe fitting is installed, the elastic telescopic part is in close contact with the surface of the first support ring 3 or the second support ring 4, which can improve the sealing of the installation of the end of the butt-jointed pipe fitting, and the elastic telescopic part can provide a certain elastic support for the butt-jointed pipe fitting to prevent the threaded connection of the butt-jointed pipe fitting from easily loosening.

[0020] In one embodiment, specifically, the elastic telescopic member includes a sliding rod 6 slidably installed inside the first support ring 3 or the second support ring 4, the end of the sliding rod 6 close to the grooved equal-diameter tee port is connected to a sealing gasket 7, the end of the sliding rod 6 away from the grooved equal-diameter tee port is connected to a retaining ring 8, a spring 9 mounted on the outer ring of the sliding rod 6 is installed between the retaining ring 8 and the first support ring 3 or the second support ring 4, and the sealing gasket 7 and the retaining ring 8 are both slidably mounted on the outer rings of the first connecting tube 1 and the second connecting tube 2.

[0021] When installing, the end of the pipe fitting that is connected to the grooved equal-diameter tee contacts the sealing gasket 7. During the rotating installation process of the butt-jointed pipe fitting, the sealing gasket 7 is pushed to move. The sealing gasket 7 drives the sliding rod 6 to slide inside the first support ring 3 and the second support ring 4. The sliding rod 6 also drives the retaining ring 8 to slide on the outer ring of the first connecting pipe 1 or the second connecting pipe 2. The retaining ring 8 drives the spring 9 to expand and contract. After the butt-jointed pipe fitting is installed, the sealing gasket 7 abuts against the surface of the first support ring 3 or the second support ring 4, which can improve the sealing of the connection between the pipe fitting and the grooved equal-diameter tee port, and the spring 9 provides elastic force for movement of the threaded connection.

Multiple groups of slide bars 6 and springs 9 can improve the overall stability of the elastic telescopic member.

[0023] In one embodiment, a first connecting rod 10 is installed between the first support ring 3 and the two groups of second support rings 4, and a second connecting rod 11 is connected between the two groups of first support rings 3. The first connecting rod 10 and the second connecting rod 11 can strengthen the support strength between the first support ring 3 and the second support ring 4, and provide stable support between the first connecting tube 1 and the second connecting tube 2. The ends of the first connecting rod 10 are hingedly connected to the first support ring 3 and the outer rings of the first support ring 3, and the second connecting rod 11 is hingedly connected to the outer rings of the two groups of first support rings 3, so as to facilitate the assembly between the components.
